The farm and the animals can wait: She is already a performing star. Eleanor is one of dozens of children who sang, danced, and drummed on the stage at the Citi Performing Arts Center-Wang Theatre in Boston last month for the 20th anniversary gala of Express Yourself, an arts immersion program in Beverly for at-risk youths and children who receive Department of Mental Health support.

At the theater, children as young as Eleanor through high school age joined their adult mentors in a series of gleeful routines, with some help from members of Stomp, Blue Man Group, and other troupes. They stalked the stage dressed as zombies during Michael Jackson’s “Thriller,” bopped in pink wigs to the helium-toned “Barbie Girl,” and joined Wampanoag tribesman Annawon Weeden
in a storytelling display.

Express Yourself debuted with a modest show in the Wang Theatre lobby 20 years ago; the show has taken place on the venue’s main stage for the past several years. A nearly full house of family and friends at the gala performance cheered on the performers, many of whom were featured in a video testimonial to the positive effect of the organization.

“That’s what this program is all about — being on the big stage,” Josiah “Joe” Spaulding, the Wang Theatre’s president and chief executive, told the audience.

One week after the anniversary show, the staff, mentors, and students of Express Yourself gathered in the Beverly workshop on Rantoul Street for their annual wrap party. The room smelled like pizza and cupcakes, the back door was open to the warm spring air, and the clanging of the nearby commuter rail line filtered in periodically.

‘I like the arts ’cause they’re so creative. . . . We all want to be happy, and we are when we’re on stage.’

The show at the Wang Theatre — one night only, nearly a year in the making — is “like one of those flowers that blooms for one day,” said mentor Nic Bennett.

“A very exotic flower,” added a colleague, to group laughter.

Just before the children arrived, staff members sat around a table discussing the show and the program’s history. Mentors who were once in the program, including Bennett, Rachel Cushing, Michael Carroll, and Tracy Powers, “know the program as much as the staff’’ does, said founder Paula Conrad. “It’s like they grew up in the business.”

Conrad, a choreographer with a master’s degree in creative arts in learning, taught with jazz musician Stan Strickland
at what was then called Lesley College; they are now the organization’s executive directors. Conrad had studied in Strickland’s voice and movement therapy class, and they later ran workshops at various schools.

“We began traveling to different areas with the bongos in the back seat,” said Conrad.

Their work quickly took shape as the Express Yourself program, which has become a model of success. In 2009 Conrad and Powers, who is studying for her master’s degree in public health, represented the program at the White House, where Michelle Obama presented them with the Coming Up Taller award from the President’s Committee of the Arts and the Humanities.

Express Yourself is designed to help children who might be alienated due to behavioral or mental health issues to develop the coping skills they will need to join “the 21st-century workforce,” said Conrad.

“We have a very high standard of what we expect from the kids, creatively, collaboratively, and socially,” she said. But it is not a top-down model, she stressed: “The kids set the bar.”

After its start in the Wang Theatre lobby, the show moved to the affiliated Shubert Theatre for several years. When theater leaders told the “ExYo” staff they would be moving to the Wang’s main stage for the 2007 show, “everyone freaked,” said Conrad. “Now everyone knows how to do it.”

“It was like going from a high school baseball field right to Fenway Park,” said Bennett.

Between the Beverly space and special “off-campus” events, the program serves approximately 500 students each year, said Conrad. About 125 attend the after-school program twice a week, constructing sets in the basement and working on routines in the ground-level studio. There is a small storefront gallery for student artwork next to the main entrance on Rantoul Street.

The location has been great, said Conrad. Express Yourself has a close working relationship with nearby Endicott College, and the proximity to the train has been a logistical bonus.

Several mentors agreed that they have stayed on because of their positive experience in the program.

“Express Yourself saved my life,” said Cushing.

She proudly shared with a visitor an essay she had written about overcoming depression and how the program has become “so important to me I schedule my life around it.”

At the workshop, the students were sitting in rows, watching video footage from the Wang performance. They took a break and formed a scrum with Strickland, clapping and dancing along to “Happy,” the hit song that was a centerpiece of the big show.

At the back of the room, Danvers High School student Patrick Walsh, a new junior mentor, watched the kids dance.

In school, “things get boring,” said Walsh, who seems to know how to keep himself entertained: His hair was dyed fluorescent green. “You’ve got to have something to do.”

Though 10-year-old Tatiana Meggie-Maddrey of Lynn said she and her little brother do not usually get along, she and 7-year-old Isiah sat side by side in the front row, watching the video.
